Republican U.S. Sen. Scott Brown of Massachusetts, in his campaign for election to a full six-year term against challenger Democrat Elizabeth Warren, has spoken often about his efforts at bipartisanship in the U.S. Senate.

But was his time in the Massachusetts Senate marked by bipartisanship? What kind of legislation was important to him?

Sunday on MassLive.com and in The Sunday Republican, we'll publish a story by political correspondent Shira Shoenberg taking a look at Brown's legislative record as a rare Republican in the heavily Democratic Massachusetts State Senate. Schoenberg interviewed Senate leaders, both Democrats and Republicans, who spoke about Brown's efforts to reach across the aisle on some issues, and not so much on others.

Also upcoming in our coverage of politics: The latest in staff reporter Robert Rizzuto's live chats with congressional candidates. Rizzuto is moderating live chats with all three candidates for Massachusetts' 1st Congressional District seat. On Monday, he'll host former State Sen. Andrea Nuciforo Jr., of Pittsfield, the current Berkshire Middle District register of deeds, for a chat with the readers. That conversation will take place at noon Monday, but questions can be submitted ahead of time by emailing Rizzuto.

Brown and his Democratic opponent, Harvard Law Professor Elizabeth Warren, both also committed to chat live with MassLive.com readers. While Warren will take questions on Friday, Aug. 3 at 1:30 p.m., Brown's office is still coordinating a date.
